Mechanisms compared
Vardenafil: Der Wirkmechanismus ist identisch mit dem von Levitra: Vardenafil hemmt selektiv die PDE5 in der glatten Muskulatur des Penis, sodass das während der sexuellen Erregung produzierte zyklische GMP akkumulieren kann. Cetirizine: Cetirizin blockiert selektiv periphere H1-Histaminrezeptoren und antagonisiert die Wirkungen des aus Mastzellen freigesetzten Histamins bei allergischen Reaktionen.
